V0 Calibrated and extruding!

 After over a month of building, it has finally started extruding plastic (well, PLA anyway). A few notes.

• Make sure the PTFE tube into the hotend is PUSHED in ALL the WAY. I use a spare print to mark on the PTFE tube where it should end up. If it does not, you will get clicks in the extruder and jams. 
• Run the bed levelling and the Z calibration multiple times, not just once. 
• Am playing with the Prusaslicer settings now, but intent is to eventually use Simplfy3D once I can get the Prusaslicer settings dialled in. 

Currently printing the test cube now at very preliminary setting of 0.3mm layer height 60mm print speed and 20% infill. 50 minutes print time.
